We installed mcafee anti-virus on our pc. As soon as this software was installed I lost access to my internet on the computer I had installed it on. I powered down my computer, turned off my router and modem and rebooted. I still did not have access. My router was able to send out wireless signals to other laptops within my house and was capable of being pinged by our ISO provider so the issue was purely with this computer. I called up mcafee support as to what might be causing this issue and they told me to install a patch by accessing my email. However, since I did not have access to the internet I was unable to access this patch. I then uninstalled McAfee with fears of firewall conflicts with my router, but this still didn’t improve the situation.

I then opened my command prompt and confirmed I was not able to ping any other website. I then ran the following commands to rebuild my ip configuration.

Ipconfig/flushdns

Ipconfig/registerdns

Ipconfig/release

Ipconfig/renew

I still could not log on and the ip address on the computer began with 169.254 instead of 192.168.

I’m still unable to get online, but can’t help but to think that this all started when I downloaded and installed mcafee.

Please verify if you have removed McAfee completely off the PC by going through programs and features list – Ensure McAfee is nt listed . Alternatively, McAfee programs would be disabled in safe mode with networking .

Please restart your PC and while it restarts, keep tapping the F8 key.

I check on our IP address and noticed an address starting with 162..254, which seemed to indicate a “stacked IP”, which I found out occurred with other McAfee installations on discussion boards.

I then ran the following commands to flush my current ip configuration.

Ipconfig/flushdns

Ipconfig/registerdns

Ipconfig/release

Ipconfig/renew

I still could not log on and the ip address on the computer began with 169.254 instead of 192.168.

I tried to rebuild the IP configuration within my registry, which DID NOT work.

We bought and installed a network card, which did NOT resolve anything.

We purchased a new router, which did NOT resolve anything.

Finally, we purchased a new Operating System and re-installed Windows which DID resolve the issue, which proved it had nothing to do with any of our equipment.

I can't believe Mcafee could not even help me with this issue.

I purchase a renewal product from Mcafee that terminated my ablity to connect to the internet and cost me a fortune to figure out and correct!
